C0244

Part 2 Of 2:

CIRCUIT DESCRIPTION
Traction Control is simultaneously controlled by the EBTCM and the ECU. The PCM sends a Delivered Torque message via a Pulse Width Modulated (PWM) signal to the Electronic Brake and Traction Control Module (EBTCM) confirming the delivered torque level for proper Traction Control system operation. The EBTCM supplies the pull up voltage.

CONDITIONS FOR SETTING THE DTC
DTC C0244 can be set anytime when ignition voltage is present. A malfunction exists if the PWM signal is out of range or no signal is received for a period of 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ A malfunction Diagnostic Trouble Code (DTC) is stored.
^ The TCS is disabled.
^ The TO indicator is turned on. The ABS remains functional.

CONDITIONS FOR CLEARING THE DTC
^ Condition for DTC is no longer present and scan tool clear DTC function is used.
^ 100 ignition cycles have passed with no DTC(s) detected.

DIAGNOSTIC AIDS
^ It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.

^ If an intermittent malfunction exists refer to "General Electrical Diagnostic Procedures" in Diagrams.

^ Possible causes for DTC C0244 to set:
- Open in the delivered torque circuit.
- The delivered torque circuit shorted to ground or voltage.
- Communication frequency problem.
- Communication duty cycle problem.
- The delivered torque circuit has a wiring problem, terminal corrosion, or poor connections.
- EBTCM not receiving information from the Engine Control Module (ECM).

TEST DESCRIPTION
The numbers below refer to step numbers on the diagnostic table.
4. Checks for proper delivered torque value.
6. Checks for the presence of a pull-up voltage from the EBTCM.
